code:
#include
int servoPin = 9;
Servo servo;
int angle = 0; // servo position in degrees
void setup() {
servo.attach(servoPin);
}
void loop() {
// scan from 0 to 180 degrees
for(angle = 0; angle < 180; angle++) {
servo.write(angle);
delay(15);
}

// now scan back from 180 to 0 degrees
for(angle = 180; angle > 0; angle--) {
servo.write(angle);
delay(15);
}
}
